qcacmn: Disable monitor peer attach when feature is disabled

Currently there is an attempt to allocate monitor
peer even when the feature is disabled, thereby leading
to an attempt to allocate 0 bytes. the failure in this
allocation propagates back and prints an error message
which can be misleading.

Disable monitor peer attach when the below feature is disabled.
- WLAN_TX_PKT_CAPTURE_ENH
- FEATURE_PERPKT_INFO
